Is Coenzyme Q10 Supplementation Exercise Performance Randomized Trial safe?

The current Migaku evidence database contains 2 reusable source documents for Coenzyme Q10 Supplementation Exercise Performance Randomized Trial. This answer focuses on safety, limits, and clinician-discussion contexts. - NT-proBNP increased post-Ex1 (19.66%, p = 0.001), post-Ex2 (12.09%, p = 0.001) but decreased in 24 h-Ex1 (- 20.28%, p = 0.001), 24 h-Ex2 (-20.83%, p = 0.001) compared to post-Ex1&Ex2, respectively. [Rahimi MR (2025); evidence level 2] - Time to fatigue (TTF) improved post-supplementation (- 0.5%, p = 0.002), whereas the placebo showed no change (- 0.08%, p = 0.793). [Rahimi MR (2025); evidence level 2] - Conclusions CoQ10 supplementation significantly reduced post-exercise cardiac stress markers (GDF-15, NT-proBNP, hs-TnT) and improved TTF in athletes. [Rahimi MR (2025); evidence level 2] - Background Coenzyme Q10 (CoQ10), a vital mitochondrial antioxidant, may enhance cardiovascular recovery and delay fatigue in athletes. [Rahimi MR (2025); evidence level 2] - The reduced form of CoQ 10 , ubiquinol (UQH 2 ), has greater bioavailability than ubiquinone, but the effects of UQH 2 supplementation on mitochondrial respiratory function and exercise capacity are unclear. [Acton JP (2026); evidence level 4] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
